: need info on best way to lay up boiler or vaporivor for up to 6 months as to protect fire side of tubes.
: any suggestions? please reply

: I'm assuming you are talking about a firetube package boiler that you are laying up for the summer. The best option is a dry lay up. Dump the boiler, open it up, inspect it, do any maintenance now so its ready for next season. Don't forget to drain the water column and low water cut out. It is a good idea to disassemble and clean them out. Also drain the DA and condensate lines. I wouldn"t want 6 month old stagnant water getting to the boiler. I would clean the firesides and if your really worried about fire side corrosion, get a tarp to put on the stack to keep out rain. As for the water sides drain the boiler completely and make sure it is dry. I have seen plants that leave them open, and some that close them back up dry. Another thing sometimes done is to install dessicant bags in the water sides to keep moisture out. But most smaller plants don't bother with it. Just keep an eye out for corrosion, rust etc.. taking place. I would recommend checking at least every other day.
